[$] Grabbing file descriptors with pidfd_getfd()

5 év 6 hónap óta
In response to a growing desire for ways to control groups of processes from user space, the kernel has added a number of mechanisms that allow one process to operate on another. One piece that is currently missing, though, is the ability for a process to snatch a copy of an open file descriptor from another. That gap may soon be filled, though, if the pidfd_getfd() system-call patch set from Sargun Dhillon is merged.

Maddock: The End of Indie Web Browsers

5 év 6 hónap óta
Samuel Maddock writes that the adoption of the "encrypted media extensions" by the World Wide Web Consortium has had just the sort of effect that people were worried about four years ago. "No longer is it possible to build your own web browser capable of consuming some of the most popular content on the web. Websites like Netflix, Hulu, HBO, and others require copyright content protection which is only accessible through browser vendors who have license agreements with large corporations."

Firefox 72.0.1 released

5 év 6 hónap óta
There is another Firefox release out there; this advisory suggests that updating quickly would be a good idea: "Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type confusion. We are aware of targeted attacks in the wild abusing this flaw."

Firefox pkg for 6.6-stable will not receive latest updates. [Updated]

5 év 6 hónap óta
An update has now been committed to the -stable branch for the latest firefox version, and the package is available for updating!

Previously, solene@ wrote:
Dear OpenBSD users, due to Firefox being too complicated to package (thanks to cbindgen and rust dependencies) on the stable branch (as this would require testing all rust consumers), the 6.6-stable branch won't receive updates for www/mozilla-firefox, so it will remain vulnerable to MFSA2020-03 and vulnerabilities that may appear after.

[$] Toward a conclusion for Python dictionary "addition"

5 év 6 hónap óta
One of Guido van Rossum's last items of business as he finished his term on the inaugural steering council for Python was to review the Python Enhancement Proposal (PEP) that proposes a new update and union operators for dictionaries. He would still seem to be in favor of the idea, but it will be up to the newly elected steering council and whoever the council chooses as the PEP-deciding delegate (i.e. BDFL-Delegate). Van Rossum provided some feedback on the PEP and, inevitably, the question of how to spell the operator returned, but the path toward getting a decision on it is now pretty clear.

[$] The trouble with IPv6 extension headers

5 év 6 hónap óta
It has taken longer than anybody might have liked, but the IPv6 protocol is slowly displacing IPv4 across the Internet. A quick, highly scientific "grep the access logs" test shows that about 16% of the traffic to LWN.net is currently using IPv6, and many large corporate networks are using IPv6 exclusively internally. This version of the IP protocol was designed to be more flexible than IPv4 in a number of ways; the "extension header" mechanism is one way in which that flexibility is achieved. A proposal to formalize extension-header processing in the kernel's networking stack has led to some concerns, though, about how this feature will be used and what role Linux should play in its development.

Ingebrigtsen: Whatever Happened To news.gmane.org?

5 év 6 hónap óta
Lars Ingebrigtsen provides details on the current status of the Gmane archive server and asks for feedback on whether it is still useful. "Over the past few years, people have asked me what happened to Gmane, and I’ve mostly clasped my hands over my ears and gone 'la la la can’t hear you', because there’s nothing about the story I’m now finally going to tell that I don’t find highly embarrassing. I had hoped I could just continue that way until I die, but perhaps it would be more constructive to actually tell people what’s going on instead of doing an ostrich impression." (Thanks to Giovanni Gherdovich).

[$] Removing the Linux /dev/random blocking pool

5 év 6 hónap óta
The random-number generation facilities in the kernel have been reworked some over the past few months—but problems in that subsystem have been addressed over an even longer time frame. The most recent changes were made to stop the getrandom() system call from blocking for long periods of time at system boot, but the underlying cause was the behavior of the blocking random pool. A recent patch set would remove that pool and it would seem to be headed for the mainline kernel.

Kernel prepatch 5.5-rc5 and stable updates

5 év 6 hónap óta
The 5.5-rc5 kernel prepatch has been released. Linus added a note to the release announcement: "One sad piece of news I got this past week was that Bruce Evans has passed away. Bruce wasn't really ever really much directly involved in Linux development - he was active on the BSD side - but he was the developer behind Minix/i386, which was what I used for the original Linux development in the very early days before Linux became self-hosting."

On the stable-update side, 5.4.8, 4.19.93, 4.14.162, 4.9.208, and 4.4.208 are all available with another set of important fixes.
